About a year ago, I saw an article in some magazine that showed an interesting animal that looked like a crawfish in frount and a crab in back. It is a freshwater animal that lives either in Central or Soputh America (maybe both). I was hoping to get more information on them and to know if they are avaliable in the USA. Thanks in advance for any help in this,_________________Any fish that will fit into another fishes mouth................................. WILL
